I keep getting a leak at the AC unit on my 5th wheel.
We got it used three years ago. Unfortunately, near the end of our 4500 mile round trip to Texas right after we got it, the rubber roof liner went on us(peeled back 10' while we were on I-5). So, I learned how to replace a rubber roof with help from a couple friends that had worked in RV repair. Everything about the roof replacement has worked great, except the AC unit.
The first year after the roof replacement, I got a leak. Tightened it down, and that helped for a while. Wound up having to replace the foam seal. That worked thru last year. Now, I have a leak again. Nothing changed on the AC unit. When I replaced the seal last year, the roof looked and felt nice and flat where the AC mounts.
The seal is compressed about 1/2 way, like the directions say(I have all the original paperwork for the AC, including installation). If I tighten it more, it will tighten the AC weep holes will be against the rubber roof.
My wife thinks we should just caulk around the seal.. The directions don't say to do that, and neither did my RV repair buddies(have lost contact with them; they both moved).
I'm not sure what to do...
Anyone had a solution to a problem like this? I'll try to get some pictures in the AM.
